A star of the teen drama series “Riverdale” apologized after he was accused of fat-shaming people years ago with a series of recently unearthed tweets.

Charles Melton issued the mea culpa Tuesday after screengrabs showing numerous insulting comments from 2011 and 2012 began to circulate on social media.

“I’m truly sorry for making inconsiderate comments several years ago and apologize to anyone I hurt,” Melton told Us Weekly in a statement. “What I posted and said was immature, offensive and inappropriate. I am ashamed of how I acted and there is no excuse for that behavior. I’m striving to do better and will use this experience to grow, helping others to understand how these types of statements are completely unacceptable.”

Melton, 27, did not confirm or deny whether all of the screengrabs that have appeared online in recent days are legit.

One of the tweets that he allegedly shared in 2012 says, "Fat chicks need to understand that wearing yoga pants is a privilege, not a right."

Another screengrab, meanwhile, reads, "Headed to the gym... Word of wisdom of the day, if you're fat... don't look in the mirror.”

Melton did not land his first professional acting role until 2014, when he appeared on an episode of “Glee” in a small part. He would’ve been around 20 or 21 at the time of the tweets.

Reps for “Riverdale” and The CW, which airs the show, did not immediately respond to a request for comment.

The actor joined “Riverdale” last year to portray Reggie Mantle – a character played by Ross Butler in the show’s first season.
